Children who have status epilepticus have continuous or rapidly repeating seizures that may be life-threatening and may cause life-long changes in brain and behavior. The extent to which status epilepticus causes deficits in auditory discrimination is unknown. A naturalistic auditory location discrimination method was used to evaluate this question using an animal model of status epilepticus. Male Sprague-Dawley rats were injected with saline on postnatal day (P) 20, or a convulsant dose of pilocarpine on P20 or P45. Pilocarpine on either day induced status epilepticus; status epilepticus at P45 resulted in CA3 cell loss and spontaneous seizures, whereas P20 rats had no cell loss or spontaneous seizures. Mature rats were trained with sound-source location and sound-silence discriminations. Control (saline P20) rats acquired both discriminations immediately. In status epilepticus (P20) rats, acquisition of the sound-source location discrimination was moderately impaired. Status epilepticus (P45) rats failed to acquire either sound-source location or sound-silence discriminations. Status epilepticus in rat causes an age-dependent, long-term impairment in auditory discrimination. This impairment may explain one cause of impaired auditory location discrimination in humans. 相似文献

The mediating role of self-efficacy in the development of entrepreneurial intentions 总被引:4,自引:0,他引:4
The purpose of this study was to investigate the mediating role of self-efficacy in the development of students' intentions to become entrepreneurs. The authors used structural equation modeling with a sample of 265 master of business administration students across 5 universities to test their hypotheses. The results showed that the effects of perceived learning from entrepreneurship-related courses, previous entrepreneurial experience, and risk propensity on entrepreneurial intentions were fully mediated by entrepreneurial self-efficacy. Contrary to expectations, gender was not mediated by self-efficacy but had a direct effect such that women reported lower entrepreneurial career intentions. The authors discuss practical implications and directions for future research. 相似文献

The Florida Department of Transportation used a series of changeable-message signs that functioned as freeway guide signs to divert traffic to Universal Theme Park via one of two eastbound exits based on traffic congestion at the first of the two exits. An examination of crashes along the entire route indicated a statistically significant increase in crashes at the first eastbound exit following the actuation of the system. Furthermore, all of the crashes occurred in close proximity to the exit gore (the crosshatched area at exits that drivers are not supposed to enter or traverse) at the first exit. In Experiment 1, behavioral data were collected using an alternating treatments design. These data revealed that reassigning the exit signs was effective in producing a change in the percentage of drivers using each of the two exits. These data also showed that the reassignment of the theme park exit was associated with an increase in the percentage of motor vehicle conflicts that consisted of vehicles cutting across the exit gore. An analysis revealed that the method used for switching the designated or active theme park exit on the series of changeable-message signs led to the presentation of conflicting messages to some motorists, thus resulting in erratic driving behavior (cutting across the exit gore). In Experiment 2, the treatment evaluated the use of a phased method of switching the designated theme park exit to eliminate the delivery of conflicting messages. The new method for switching the designated theme park exit was not associated with an increase in motorists cutting across the exit gore. 相似文献

现代新儒家的基本理论主张可概括为 :儒学主流说、儒家道统说、新内圣外王之道、良知自我坎陷说、儒学复兴论。现代新儒学第三代重要代表人物已经偏离或放弃了这些基本的理论和主张 ,走上了文化多元化之路。这无疑意味着现代新儒学基本理论的自我消解。现在 ,这股文化思潮的高峰已经过去 ,已经成为历史。 相似文献

小学4~6年级儿童对同伴亲社会行为动机的评价 总被引:8,自引:0,他引:8
随机选取衡水市358名4~6年级小学生,采用问卷法探讨其对同伴做出帮助行为、分享行为、合作行为、安慰行为等四种亲社会行为动机的评价。结果发现。这些儿童认为其同伴的亲社会动机主要是“乐于助人”、“为他人着想”、“应该这么做”、“获得好朋友”;他们普遍认为同伴的亲社会动机是出于对他人和集体利益的考虑:总体上女生比男生更倾向于从利他和集体利益的角度评价同伴的亲社会动机,特别在合作行为和安慰行为方面;各年级的评价之间没有显著差异。 相似文献

对复归与走近马克思的考辨--一种现代解释学意义上的新破解 总被引:2,自引:0,他引:2
本文针对当今“复归”、“走近”马克思的观点,运用当代解释学进行了新破解。本文依据马克思哲学的根本原则,运用当代解释学的积极合理成果,立足于现代思维范式的新视域,对建国以来理解马克思哲学的三个不同阶段、不同结果进行了新破解,肯定了三个不同阶段及结果的合理性及存在的价值,明确指出破解对马克思哲学理解的理解,必须摒弃形而上学的“非此即彼”、以及追求那种所谓“马克思哲学本真精神”的绝对思维方式。运用独特的新视角,指出对马克思哲学的理解是一个开放的过程,这一过程的不同阶段及结果,只要实现了实践、理解主体、理解对象三者的具体、历史统一,就都具有真理性,就都是马克思哲学本真精神的显现;与此同时,还通过这一问题的探索揭示出了该过程的内在逻辑。 相似文献

The authors conducted an empirical study in research and development centers and research-oriented commercial companies in Singapore to test a model for understanding individuals' technical information inquiry behavior in organization settings. Individual-level antecedents (learning orientation, risk-taking propensity, and self-efficacy) and perceived contextual-level antecedents (management support, relationship quality, organizational norms favoring technical information inquiry, and accessibility of the information source) were theorized to affect one's evaluation of the potential benefits and costs in making technical information inquiries. The results showed that the perceived norms favoring technical information inquiry affected the willingness of individuals to make technical information inquiries through the mediating variable, expectancy value. In addition, compared with individual-level variables, perceived contextual-level variables explained slightly more variance in the willingness to make technical information inquiries. Theoretical and practical implications are discussed. 相似文献

非语义性命名障碍:一个认知神经心理学的个案研究 总被引:4,自引:0,他引:4
本研究从认知神经心理学的角度,根据有关语言产生和词汇认知的理论,对一例脑损伤病人的命名障碍进行了较为细致的个案分析,研究表明:(1)命名障碍可分为语义性和非语义性两类;(2)病人LY的命名无能主要不是因为其语义系统受到损害,而是因为其语音提取受到损害,以致于恰当的语义激活不能激活恰当的语音表征;(3)LY在汉字阅读中的表现也表明了字形信息在词义激活中的重要性。 相似文献

Many philosophers assume that, when making moral decisions under uncertainty, we should choose the option that has the greatest expected moral value, regardless of how risky it is. But their arguments for maximizing expected moral value do not support it over rival, risk-averse approaches. In this paper, I present a novel argument for maximizing expected value: when we think about larger series of decisions that each decision is a part of, all but the most risk-averse agents would prefer that we consistently choose the option with the highest expected value. To the extent that what we choose on a given occasion should be guided by the entire series of choices we prefer, then on each occasion, we should choose the option with the highest expected moral value. 相似文献
